Of course the trick is to tell which is which. According to the pg_dump
code the current rule is
* As per discussion we dump casts if one or more of the underlying
* objects (the conversion function and the two data types) are not
* builtin AND if all of the non-builtin objects are included in the dump.
* Builtin meaning, the namespace name does not start with "pg_".
Possibly Oliver is falling foul of that rule somehow --- it's certainly
not perfect, especially in a partial dump scenario.
